General Description
The CLC411 combines a state-of-the-art complementary bipolar
process with National’s patented current-feedback architecture to
provide a very high-speed op amp operating from ±15V supplies.
Drawing only 11mA quiescent current, the CLC411 provides a
200MHz small signal bandwidth and a 2300V/ s slew rate while
delivering a continuous 70mA current output with ±4.5V output swing.
The CLC411’s high-speed performance includes a 15ns settling time
to 0.1% (2V step) and a 2.3ns rise and fall time (6V step).
The CLC411 is designed to meet the requirements of professional
broadcast video systems including composite video and high definition
television. The CLC411 exceeds the HDTV standard for gain flatness
to 30MHz with it's ±0.05dB flat frequency response and exceeds
composite video standards with its very low differential gain and
phase errors of 0.02%, 0.03°. The CLC411 is the op amp of choice
for all video systems requiring upward compatibility from NTSC and
PAL to HDTV.
The CLC411 features a very fast disable/enable (10ns/55ns) allowing
the multiplexing of high-speed signals onto an analog bus through the
common output connections of multiple CLC411’s. Using the same
signal source to drive disable/enable pins is easy since “break-
before-make” is guaranteed.
The CLC411 is available in several versions:
CLC411AJP
CLC411AJE
CLC411A8B
CLC411AMC

... In particular, the feedback resistor should have its shortest lead on the inverting input side of the CLC411. The output is less sensitive to parasitic capacitance and therefore can drive the longer of the two feedback resistor connections. The evaluation board available for the CLC411 (part #730013 for through-hole packages, 730027 for SO- 8) may be used as a reference for proper board layout ...
